Hi there. I am now building a self-paced reading task with a YES/NO comprehension question. My problem now is get these sentences presented across four counterbalanced lists so that participants always see one target in only one of the four conditions. I already created the four lists in four separate excels, but don’t know how to achieve this on the builder? Could you help me with that? Thanking in you in anticipation. The four headers in the excel are Sentence/followUp/Question/CorrAns. I have also attached the screenshot of the builder. ! 
Thanks!
